| Researchers at Purdue University have developed a new battery state monitoring system to enhance performance, avoid failure, and prolong lifetime for batteries in electronic vehicle and energy storage system applications. This approach measures states of charge (SoC) and health (SoH) in batteries with higher accuracy and speed than current technologies. Purdue researchers implement an ampere hour counting (AHC) approach that induces a magnetic field to quantify the electrochemical state of batteries. In addition, this technique makes up for Eddy current loss in measuring SoH by opening charging discharging paths during inductive coil excitation. Advantages: -Accurate -High Speed -Noninvasive Potential Applications: -Electronic Vehicles -Energy Storage Systems Technology Validation: Testing compared with current technology |
